2 month ago
Product details
The K3V280DTH piston pump (plunger pump) equipped on the Volvo 750D is a high-pressure hydraulic pump produced by Kawasaki. It is primarily used in the main hydraulic systems of construction machinery such as excavators, featuring high pressure, durability, and stability. It is suitable for large excavator models like the Volvo EC700 and EC750.
I. Product Background
• Brand and Model: The K3V280DTH is part of Kawasaki's hydraulic pump series and is a swashplate-type axial piston pump widely applied in the construction machinery field.
• Application Models: This pump is mainly used in large excavators from Volvo, such as the EC700 and EC750, serving as the main hydraulic pump to provide power.
• Core Function: It converts mechanical energy into hydraulic energy to drive the hydraulic system of excavators, enabling actions such as digging, swinging, and traveling.
II. Technical Characteristics
1. High-Pressure Design:
• The K3V280DTH is a high-pressure hydraulic pump capable of withstanding significant working pressures, meeting the power demands of large excavators.
• It is suitable for high-load, high-intensity operating environments, such as mining operations and large-scale earthmoving projects.
2. High Durability:
• The pump body is made of high-strength cast steel, and key components (such as pistons, cylinders, and port plates) are precision-machined and heat-treated, offering excellent wear resistance and fatigue performance.
• It has a long design life and can operate stably under harsh conditions, reducing maintenance and replacement frequency.
3. High Stability:
• Its swashplate-type structural design, combined with advanced hydraulic control technology, ensures stable output flow and pressure from the pump, minimizing shocks and vibrations in the hydraulic system.
• It is suitable for precision operations that require high stability in the hydraulic system.
4. Strong Adaptability:
• The K3V280DTH can seamlessly match the hydraulic systems of Volvo excavators, ensuring coordinated performance of the entire machine.
• It is also adaptable to other brands of construction machinery, but specific model matching is required.
III. Application Scenarios
• Large Excavators: Such as the Volvo EC700 and EC750, used in heavy-duty operations like mining, large-scale earthmoving, and infrastructure construction.
• Other Construction Machinery: Such as rotary drilling rigs and cranes that require high-pressure hydraulic systems.
IV. Market Situation
• Price Range: The price of the K3V280DTH hydraulic pump varies depending on the supplier, region, and purchasing channel. Market prices typically range from several thousand to tens of thousands of yuan.
• Purchasing Channels: It can be purchased through Volvo's official parts channels, Kawasaki-authorized dealers, or professional construction machinery parts markets.
• After-Sales Service: It is recommended to choose suppliers that offer formal quality assurance and after-sales service to ensure product quality and long-term reliability.
V. Maintenance and Care
• Regular Inspections: Regularly check the oil level, oil quality, and sealing of the hydraulic pump to ensure the cleanliness of the hydraulic system.
• Replace Hydraulic Oil: Change the hydraulic oil according to the manufacturer's recommended intervals to prevent pump wear caused by oil contamination.
• Professional Repairs: If a decrease in pump performance or abnormal noise is detected, promptly contact professional repair personnel for inspection and repair.
